Aventurine has the summer update for you. While we'll stop short of categorizing the Greek developer's PvP-centric Darkfall as a whimsical game, there is no denying the fact that its developers are packing a sense of humor into the title along with all the blood spurts and horrific sound effects.
Resfelm, Aventurine's community liaison, brings us word of a new craftable vehicle called the Fun Hulk, and while it's not green, prone to fits of anger, or the star of a bad Ang Lee film, it does feature the aforementioned cannon and is much easier to craft than a full-sized warhulk.
In addition to the vehicle, Darkfall's devs are introducing new items called Use Flags (which when used in conjunction with your new ride) provide you with the tools to set up your own starting line, finish line, and waypoints. This being Darkfall, player racing events are more likely to resemble Death Race 2000 than Mario Kart, as the Fun Hulks can damage other Fun Hulks and can take damage from anything.
